Internet security is a set of measures aimed at safeguarding personal information, protecting devices, and preventing digital threats. With the continuous growth of online services and remote work, security issues have become critically important for every user.

Main Threats

Modern users face a variety of cyber threats:

• Viruses and malware: can damage files, slow down system performance, or steal confidential data (more details — do you need antivirus on a home PC).
• Phishing: attackers create fake websites, emails, and messages to trick users into entering logins, passwords, and bank details.
• Spyware: secretly collects information about user activity, keystrokes, and visited websites.
• Data leaks: occur due to service breaches or careless handling of personal information.

Protection Principles

Following basic rules significantly reduces risks:

1. Regularly update your operating system, browsers, and applications.
2. Use strong, unique passwords for every service.
3. Enable two-factor authentication wherever possible.
4. Be cautious when clicking links or downloading files from unknown sources.

Public Wi-Fi Networks

Public Wi-Fi networks in cafes, airports, and hotels often lack adequate protection. Attackers can intercept traffic or manipulate connections.

To enhance security, it is recommended to:

• Avoid entering passwords and payment information.
• Use secure HTTPS connections.
• Connect through a VPN to encrypt your traffic.

Browser and Online Account Protection

The browser is the primary tool for working online and is often a target for attacks.

It is recommended to:

• Install extensions only from official sources.
• Regularly check plugin permissions (browser extension risks).
• Use password managers for secure storage of login credentials.

Data Backup

Even when following all security measures, the risk of data loss cannot be completely eliminated.

To protect information:

• Create backups on external drives.
• Use encrypted cloud storage.
• Regularly verify the relevance of backups.

Conclusion

Internet security depends not only on technology but also on user behavior. A conscious approach, adherence to basic rules, and the use of trusted tools significantly reduce the risks of data leaks and cyberattacks. Additionally, we recommend exploring: Android and iOS security.
